Apex converter boxes are on sale at BB. They have the original DT250, the DT502 (new firmware but no longer able to manually enter channels?) and now the DT250A. The saleman wasn't aware the DT250A existed but once I showed him, he assumed they fixed some bugs. I just saw a mention of it on another forum but no details. I'd like to pick one up but if I can't manually change channels, I'd prefer an old 250. Does anybody know what the 250A does differently? Thanks!
